    Will I go bald?

    The genetics of going bald can be inherited from both sides of the family.

    Since androgenetic alopecia is not a simple form of inheritance, male baldness might not affect close relatives.

    Therefore, you might go bald even if you do not have bald parents.

    Frequently Asked Questions

    The hormones in hair follicle are responsible for hair loss in cases of genetic male baldness.

    The main hormone involved in men’s baldness is dihydrotestosterone (DHT).

    Although DHT is directly related to androgenetic alopecia, DHT blood levels are usually normal in bald people.

    Normal DHT blood levels are expected even in advanced or fast progression hair loss.

    Therefore, hormonal disturbances are not expected in people who are going bald.

    An exception is the use of steroids.

    The use of steroids can contribute to the progression of baldness and cause hormonal disturbances.

    The progression of hair loss in androgenetic alopecia depends on a lot of aspects.

    Age of onset

    Young men who start losing hair before 18 have more chances of going bald.

    When hair loss starts around 30 or 40, the evolution of hair loss is usually slower and milder.

    Miniaturization rate

    Androgenetic alopecia usually takes years to be noticed.

    When men have a fast progression of hair loss, it can be a sign of severe baldness.

    Baldness size area

    Larger areas of hair loss are likely to progress to baldness.

    Ultraviolet radiation exposure causes repetitive sunburn on the scalp, which can lead to skin cancer.

    Scientific studies supports a link between baldness and some medical conditions such as: hypertension, heart diseases, obesity, infertility and prostate cancer.

    Male baldness can be controlled. The best chances of a successful treatment depend on how early the baldness is diagnosed and treated.

    It is recommended to make an appointment with your doctor as soon as you noticed the first signs of hair loss.
